Magic: The Gathering‘s recent batch of Tarkir: Dragonstorm previews have shown off a correction to one of the game’s creature types that was originally introduced in the 2014 set, Khans of Tarkir. The original set introduced Tarkir’s five clans, each inspired by a different historical culture from across Asia.

Now, Tarkir: Dragonstorm is taking steps to fix that original mistake.
